I’m looking at a video of Capture One and I see what it is doing, but I’m not sure it’s fundamentally different from the Nitro corrector, with two differences:
1) The amount of correction can be controlled (so you can specify the correction, but then only apply a portion of it)
2) The amount of crop looks to be controllable also.
3) the interface is different – it looks like it places four points on the image and then you use sliders to move the points around.
I cannot say whether it’s better than simply placing four points on the image. Perhaps the Nitro UI needs to be less general purpose since you can do basically anything with four points.
The amount of crop is something I am going to provide control over, so it won’t remove as much of the image.
